CUSTOMIZED ARTIFICIAL NAIL - Method and system for designing and making one or more artificial nails customized to fit one or more real nails of a client are disclosed. Additionally, the invention enables customization or selection of decorative patterns for the artificial nail. The process begins with scanning one or more nails of the client with a scanner. The scanned image is then converted into a virtual three-dimensional surface model for each real nail. The virtual three-dimensional model of each nail is displayed on a monitor of a workstation. The user, e.g. a beautician at a beauty saloon, using the workstation and in consultation with the client, designs a customized artificial nail using the virtual three-dimensional model of the real nail. At the user command, the customized design of the artificial nail is then sent to a numerically controlled (NC) or a similar machine, where the artificial nail is made in accordance with the custom design. The artificial nail may be made from acrylic materials or other suitable materials.

BRACKET-SLOT-TO-WIRE PLAY COMPENSATION ARCHWIRE DESIGN - A method and workstation are described for designing compensation in an orthodontic archwire in order to offset the bracket-slot-to-wire play and realize the disered displacement in a tooth from an initial position to the target position. Bracket-slot-to-wire play can reduce the effectiveness of an archwire in bringing the teeth of an orthodontic patient from malocclusion to desired target. Bracket-slot-to-wire play is the difference in volume between the size of a bracket slot, which is larger than the size of the archwire, and the size of the sliding segment of an archwire inserted in the bracket slot. Customized archwires comprise alternating sliding segments interconnected by segments with bends and/or twists in three-dimensional space. The sliding segments are placed in the bracket slots and exert forces on the brackets created by the segments with bends and/or twists for moving the teeth towards the target positions.

COMPENSATION ORTHODONTIC ARCHWIRE DESIGN - Method and workstation automatically designing an arch-wire including compensations for auxiliary appliances or biological constraints exerting unknown forces to achieve a pre-planned treatment goal are disclosed. The adjusted customized arch-wire is designed after an initial customized arch-wire has been used to treat a patient and is at or near equilibrium. The initial custom arch-wire is first designed by producing a 3D computer-based, geometrical model of a patient's dentition, locating brackets on the digital tooth model, moving the digital tooth models to planned final positions and orientations, and then calculating a wire which fits in the slots of the brackets while the teeth are in their planned final positions and exerts no forces on the brackets. After a period of time the teeth will move under the force of the wire and will eventually move into positions such that the forces from all appliances and biological systems are in equilibrium. If the teeth are not in the final planned positions at that point in time, the adjusted custom arch-wire is designed and applied.
